The XM1111 Mid-Range Munition (MRM) was a 120 mm precision guided munition developed for the Rheinmetall 120mm Gun (known as the "M256" in the US military) used by several Western tanks. It was also intended to fulfill a requirement for Future Combat Systems (canceled) for a long-range, Beyond Line of Sight tank munition.
In December 2007, Raytheon's CE-based concept was awarded the system-design-and-development contract to develop the round. Valued at $232.3 million, the 63-month contract covers system design and development.
The missile/projectile was designed to be used as a high-velocity penetrator for line-of-sight and beyond-line-of-sight shots. In line of sight, it would operate using laser guidance or a millimeter wave seeker. In BLOS, the shell would be fired in a ballistic arc, and would seek out its own targets.
- April 2004: Successful test firing of the system.
- May 2006: Successful high Mach flight maneuver test at Yuma Proving Grounds.
- July 2007: ATK Forms "Team MRM" to compete for the U.S. Army's XM1111 Mid-Range Munition Program.
The missile/projectile was to be a high-velocity multiple-mission projectile for line-of-sight and beyond-line-of-sight shots. In line of sight, it would operate using laser guidance or an uncooled imaging infrared seeker (IIR). In BLOS, the shell would be fired in a ballistic arc, and would glide to seek out its own targets. The BLOS mission could be autonomous or use FO directed target designation.
Mid-Range Munition incorporated proven technology using a dual-mode seeker suite comprising an imaging infrared sensor and a digital semi-active laser seeker. The dual-mode seeker was developed and successfully demonstrated during a two-year, Army-managed science and technology program. MRM-CE refined seeker technology developed as part of the XM1007 Tank Extended Range Munition (TERM) program.
For a beyond-line-of-sight mission, the chemical energy warhead was a better solution; with proven lethality against the primary target of threat armor, and better effects against the secondary targets of buildings, fortifications, and light armor than a less versatile kinetic energy penetrator.
- September 2006: A U.S. M1 tank fired an MRM-CE round which hit a moving T-72 tank at a range of 8,600 meters.
- March 2007: Successful test firing using dual-mode seeker fusion.
- December 2007: Raytheon Wins Army XM-1111 Development Contract.
